Abstract

An electro-mechanical clutch apparatus includes a stationary member (22,122) having a center portion extending along an axis A and a stationary coil assembly (34,134) fixed about the center portion. A rotatable member (46,146) extends along the axis A and includes an annular projection (52,152) radially spaced from the coil assembly. A ratchet surface (29,129) presents a plurality of teeth disposed in axially aligned and radially spaced relationship with the annular projection. The rotatable member includes a magnetic pole piece (62,162) disposed in radially spaced and concentrically aligned relationship with said coil assembly. The rotatable member includes a locking member (58,158) pivotably attached to the annular projection and pivotable between an engaged position in engagement with one of the teeth in response to the coil assembly being de-energized and a released position displaced from engagement with the teeth and attracted towards the magnetic pole piece in response to the coil assembly being energized.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and benefit from U.S. Provisional Patent Application Serial No. 62 / 060,625, entitled "Rotary Electromechanical Actuator or Actuator Apparatus," filed October 7, 2014, the entire disclosure of which Incorporated herein by reference. technical field [0003] The present disclosure relates generally to clutch assemblies, and more particularly, to electromechanically actuated clutch assemblies. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Automatic transmissions provide multiple forward and reverse speed or gear ratios by selectively actuating one or more brakes or clutches. One type of brake or clutch widely used in modern automatic transmissions is the one-way clutch (OWC), which operates on one of its races (in a radial clutch arrangement) or on one of its drive plates (in an...
